fix: don't compile with -march=native by default - #2
Conversation
The build unconditionally added -march=native on UNIX, so rapidjson.so inherited whatever CPU the build host happened to have. A module built on a modern packaging machine then dies with SIGILL on older CPUs, and on hypervisors that expose a baseline CPU model. Move it behind LUA_RAPIDJSON_ARCH_NATIVE (default OFF) so distributed builds are portable, and assert in CI that the built module carries no AVX instructions. Also add the release workflow used by the other api7 rock repositories: pushing a rockspec/ file to master with a "feat: release v<version>" commit tags the release and uploads it to luarocks.

luajit.org no longer serves the LuaJIT 2.0.5 and 2.1.0-beta3 tarballs, so gh-actions-lua fails with a 404 and the whole matrix has been red since 2025-08-26. Move to luajit-2.1, which the current action pulls from git, and stop fail-fast from cancelling the other entries and hiding which one actually broke.

- Around line 37-40: Update the portability check in the workflow to fail
closed: require build.luarocks/rapidjson.so to exist and ensure objdump succeeds
while capturing its disassembly with Intel syntax and no raw instruction bytes
under set -euo pipefail. Match AVX/AVX-512 mnemonics by detecting instruction
tokens beginning with v or k, including operandless instructions, and retain the
existing failure message and nonzero exit behavior.
In @.github/workflows/release.yml:
- Around line 34-40: Update the release-title regex assigned to re so it
requires exactly one literal v, captures a non-whitespace version, and anchors
the complete title through the end. Preserve the existing BASH_REMATCH outputs
and validation failure behavior.
- Around line 7-8: Update the release workflow’s trigger and upload step to use
the current root-level rockspec, package name, and declared revision. Derive the
selected rockspec filename and version from the repository’s rockspec metadata
instead of hardcoding separate filename or revision assumptions, ensuring both
change detection and publishing target the same package.
- Around line 19-25: Harden the workflow steps around actions/checkout,
leafo/gh-actions-lua, and leafo/gh-actions-luarocks by disabling checkout
credential persistence, pinning every action to an immutable full commit SHA,
and placing the setup actions in a job without contents: write permission where
feasible.

The portability check silently passed when the module was missing or objdump failed, and its pattern only matched 256-bit operands, so a build using VEX-encoded 128-bit instructions or bare vzeroupper slipped through. Assert the artifact exists, fail on a broken pipeline, and match any VEX/EVEX mnemonic instead. The release trigger matched "v*", which also accepted a version with no leading v and would have tagged it anyway.

The portability check only looked for VEX/EVEX mnemonics, so a build that targets a pre-AVX CPU passed it while still using SSE4.1 (pmovzxdq, roundsd) or SSE4.2 (pcmpistri, reachable through RAPIDJSON_SSE42) and still dying with SIGILL on older machines. Assert the recorded compile flags stay on the x86-64 baseline, and widen the disassembly scan to every instruction family above it. Restore LuaJIT 2.0 to the matrix through the luajit-2.0 alias, which builds from the version branch rather than the tarball luajit.org withdrew; it is a runtime the README claims support for. Creating the GitHub release now tolerates an existing release, so a failed luarocks upload can be re-run.

Cover the extension families a compiler cannot reach from -march but inline intrinsics could: RDRAND/RDSEED, TSX, FSGSBASE, AMX and friends. The build job runs dependency and test code, so it has no reason to keep the workflow token in .git/config.
